# Collapsed Purchase Funnel

## Definition

The compression of the traditional multi-step marketing journey — **discovery → consideration → conversion** — into a single AI context window.

## The Mechanic

In classical e-commerce and search, the user journey spans multiple sessions, surfaces, and tabs: discover via search, click through to a website to consider, then navigate to checkout to convert. Each hop is a leakage point.

Conversational AI collapses the entire funnel into one interaction. Inside the **same context window**, a user can:

1. Discover a product through the AI's recommendation,
2. Consider it by asking follow-up questions,
3. Convert immediately via embedded checkout or affiliate link.

## Why It Outperforms Traditional Funnels

The collapsed funnel rides on top of the **trust** the user has already built with the AI agent during the conversation. There is no context switch, no comparison-shopping tab, no abandonment cart. The result is materially higher conversion — quantified at ~1.5x baseline in early Criteo data ([[claim-criteo-conversion]]).

This is the substrate underneath [[concept-conversational-advertising]]. The new ad surface only matters because the funnel collapses around it.
